Now that the hard fork is done, the contract to refund your dao tokens is available but here is why I think you should keep them.
Simple reason :  I think after most people have asked for their DAO tokens to be refunded, the rarity of the remaining DAO will add value to them. Just like an old Silver or Gold coin is worth more than it's weight  of the precious metal.
Some people in 10 years might be ready to pay 100 times the price just to hold 1 DAO as a souvenir. Imagine instead of getting 1 ether for 100 DAO, get 1 ether for 1 DAO when ether is maybe $1000...
